A heating furnace with separately rotating slabs is provided to improve the quality and productivity of a hot-rolled product by improving slab roll product quality through uniformly heating the upper and lower surface of the slab. A heating furnace with separately rotating slabs(1) comprises: a heating chamber(10) including a hollow internal space, an inlet of the slab, and an outlet of the heated slab and including a burner inside to heat the inside; a push part(20) which is located at the inlet of the heating chamber and pushes the slab inside the heating chamber; a plurality of slab rotating parts(40) rotating the slab inside the heating chamber in a discrete rotation method by including a motor(75); a slab transport unit(60) in which a magnetic track(66) of a crawler-type is formed on both side walls of the heating chamber and in which a slab rotating unit moves inside the heating chamber along the magnetic track; and an extracting part(80) being located at the outlet of the heating chamber and drawing out the slab to the outside of the heating chamber. |
